In recent years,significant progress has been made in diabetes research both domestically and internationally,new diagno-sis and treatment techniques and methods have been constantly emerging,and clinical research evidence has been continuously accu-mulated and updated.To keep pace with these important developments,the Diabetes Branch of the Chinese Medical Association has ac-tively organized experts to update the China Guidelines for the Prevention and Treatment of Diabetes.This update aims to provide a more comprehensive and scientific guide for diabetes prevention and treatment,greatly promote the standardized and integrated man-agement of diabetes by clinicians,and ensure that patients receive standardized and personalized treatment plans to improve therapeu-tic outcomes and quality of life.

Over the years,the American Diabetes Association(ADA)has been actively committed to the development and promotion of standards for the diagnosis,treatment,and daily care of diabetes.Since 1989,it has updated the diabetes diagnosis and treatment standards every year,which have become one of the most authoritative guidelines in diabetes and have been recognized and adopted by various countries.On December 10,2024,the 2025 Standards of Care in Diabetes were released,incorporating the latest evidence-based medicine content related to diabetes and its complications and comorbidities.It aims to provide guidance on the diagnosis,treat-ment,and management of the condition for clinicians,patients and their families,and researchers.This article interprets the major up-dates from the Standards.

With the acceleration of population aging in China,the management of elderly patients with diabetes has become a critical issue in the field of public health.By integrating international evidence-based medical research data with the specific conditions of China,the 2024 edition of Guideline for the management of diabetes mellitus in the elderly in China proposes individualized diagnosis and treatment strategies for elderly patients with diabetes.This article gives a systematic interpretation of the guideline from a nursing perspective,with a focus on the core contents closely associated with nursing practice,and it also elaborates on the implications for nursing work,summarizes and analyzes the challenges in the management of elderly patients with diabetes,and proposes corresponding strategies,in order to provide a theoretical basis and practical guidance for implementing nursing management of elderly patients with diabetes among clinical nurses.

The Guideline for the prevention and treatment of diabetes mellitus in China(2024 edition),released by the Chinese Dia-betes Society on January 20,2025,has updated evidence on diabetes mellitus from various aspects including its epidemiological status in China,diagnosis and treatment progress,and complication management,aiming to guide and facilitate standardized comprehensive management of diabetes mellitus in clinical practice.This paper interprets the guideline from the perspective of nursing practice,focus-ing on nursing care for special diabetic conditions,lifestyle and behavioral interventions,and the procedures of relevant nursing tech-niques.We hope to provide nursing professionals with standardized guidance on diabetes prevention and treatment,thereby further standardizing and refining specialized nursing care for diabetes mellitus,enhancing the quality of patient care,and improving patient prognosis.

OBJECTIVE To provide certain therapeutic ideas and references for the pharmaceutical care of severe Legionella pneumonia in anti-infection treatment. METHODS Clinical pharmacists participated in the entire treatment process of a patient with severe Legionella pneumonia， and assisted clinical physicians in evaluating the infecting pathogens using the WUH （Winthrop- University Hospital criteria） scoring system， based on the patient’s clinical symptoms， physical signs， and changes in pulmonary imaging. Leveraging their pharmaceutical expertise， clinical pharmacists recommended a combination of piperacillin sodium and tazobactam with moxifloxacin hydrochloride for anti-infection treatment， and closely monitored the patient’s clinical manifestations. They promptly identified delirium and abnormally elevated levels of lipase， amylase and liver enzymes， and successively suggested adjusting the treatment plan to a combination of piperacillin sodium and tazobactam with doxycycline or azithromycin for anti- infection after analyzing the causes， along with liver protection treatment， enteral nutrition， and parenteral nutrition. Additionally， clinical pharmacists closely monitor the patient’s medication adherence and provide her with medication education. RESULTS The clinical physicians accepted the recommendations of the clinical pharmacists， and the patient improved after treatment and was discharged. A follow-up examination one month later showed no recurrence. CONCLUSIONS Clinical pharmacists， when assisting clinicians in treating severe Legionella pneumonia， not only pay attention to changes in the patient’s clinical symptoms and physical signs， but also closely monitor the adverse reactions of fluoroquinolone， tetracycline， and macrolide antibiotics. They should promptly recognize adverse reactions and provide recommendations for adjusting treatment plans， as well as offer comprehensive pharmaceutical care throughout the patient’s treatment， to ensure the effectiveness and safety of clinical therapy.

Objective We aimed to study the protective effect of total glucosides of paeony (TGP) on chemical liver injury with pattern of liver yin deficiency in rats and determine whether it exerts these effects through the phosphoinositide 3-kinase(PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway.Methods Forty male Sprague-Dawley rats were randomly divided into the following four groups: (i) the blank group, (ii) the model group, (iii) the Yiguan Jian group, and (iv) the TGP group (10 rats per group). For 6 weeks, rats in all groups except for the blank group were injected intraperitoneally with 20％ carbon tetrachloride olive oil solution and were given thyroid tablets (30mg/kg) by gavage in order to establish the model of chemical liver injury with pattern of liver yin deficiency. During the modeling period, rats in the blank and model groups were gavaged daily with distilled water, while rats in the Yiguan Jian group and the TGP group were gavaged with 635mg/kg of Yiguan Jian decoction and 50mg/kg of TGP suspension, respectively. During the administration period, the body weight and rectal temperature of rats were measured every 2 weeks. After the administration, 24-hour food intake, 24-hour water intake, and moisture capacity in tongue surface were recorded. Serum cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), interleukin-1 (IL-1), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), and interleukin-1 receptor antagonist (IL-1Ra) contents were measured by ELISA and the cAMP/cGMP ratio was calculated. Changes in the serum levels of alanine aminotransferase (ALT), alanine transaminase (AST), gamma-glutamyl transpeptidase (γ-GT), alkaline phosphatase (ALP), total bilirubin (TBIL), and total bile acids (TBA) were detected using colorimetric method. Masson staining was performed to observe the degree of liver fibrosis and to calculate the relative collagen area. Real-time PCR and Western blotting were conducted to determine the PI3K, AKT, and mTOR mRNA and protein expression levels in rat liver.Results Compared with the blank group, rats in the model group had a lower body weight at weeks 2, 4, and 6, a higher rectal temperature at weeks 2, 4, and 6, and a higher 24-hour food intake; the cAMP level was elevated, the cGMP level was decreased, and the cAMP/cGMP ratio was elevated; the contents of IL-1, IL-6, and TNF-α were elevated, and the contents of IL-10 and IL-1Ra were decreased; ALT, AST, γ-GT, ALP, TBIL, and TBA levels were elevated; the percentage of collagen area in the liver was increased; and the mRNA and protein phosphorylation levels of PI3K, AKT, and mTOR were elevated ( P<0.05). Compared with the model group, rats in the TGP group showed a decrease in rectal temperature at weeks 2, 4, and 6, a decrease in 24-hour food intake and water intake, and an increase in the moisture capacity in tongue surface; rats in the Yiguan Jian and TGP groups showed a decrease in cAMP, an increase in cGMP, and a decrease in the cAMP/cGMP, the contents of IL-1, IL-6, and TNF-α were decreased and the content of IL-10 was increased, the percentage of collagen area in the liver was decreased; ALT, AST, γ-GT, ALP, and TBIL levels were decreased in the TGP group, and PI3K, AKT, and mTOR were downregulated at the mRNA and protein levels(P<0.05).Conclusion TGP has a good protective effect on chemical liver injury with pattern of liver yin deficiency in rats. TGP may regulate the balance of yin and yang by inhibiting the PI3K/AKT/mTOR pathway, reducing the secretion of pro-inflammatory cytokines, and increasing the release of anti-inflammatory cytokines.

Objective We aimed to investigate(i)the preventive and therapeutic effects of Huogu Muli Prescription(HGMLP),a Chinese medical compound consisting of epimedii folium,drynariae rhizoma,and ostreae concha,on postmenopausal osteoporosis(PMOP)rats and(ii)whether it exerts its effects by regulating the osteoclast-osteogenesis balance.Methods Forty-eight female Sprague-Dawley rats were randomly divided into the following six groups:(i)the sham-operated group,(ii)the model group,(iii)the Qianggu Capsule group,(iv)the calcium carbonate group,and(v,vi)the HGMLP low-dose and high-dose groups(n = 8 rats per group).After adaptive feeding,rats in all groups except the sham-operated group were treated with bilateral ovarian castration to establish the PMOP model.Each day,rats in the Qianggu Capsule group received 0.054 g/kg Qianggu Capsule suspension intragastrically,rats in the calcium carbonate group received 1.670 g/kg calcium carbonate suspension intragastrically,and rats in the HGMLP low-dose and high-dose groups received 0.188 g/kg and 0.375 g/kg HGMLP intragastrically.Rats in the sham-operated group and the model group received an equal volume of normal saline intragastrically.After 90 consecutive days,serum estradiol(E2),estrogen receptor α(ERα),procollagen typeⅠN propeptide(PINP),and tartrate-resistant acid phosphatase 5b(TRACP-5b)were detected by ELISA.Total antioxidant capacity(T-AOC),superoxide dismutase(SOD),catalase(CAT),and malondialdehyde(MDA)levels were measured by colorimetry.Bone mineral density(BMD),trabecular number(Tb.N),trabecular separation/spacing(Tb.Sp),trabecular thickness(Tb.Th),and structure model index(SMI)were measured by Micro-CT,and the microstructure of cancellous bone was observed.The expressions of osteoprotegerin(OPG),receptor activator of nuclear factor-κB(RANK),RANK ligand(RANKL),phosphorylation of forkhead box O3(FoxO3α),Wnt2,β-catenin,and peroxisome proliferator-activated receptor γ(PPARγ)in rat femur tissue were detected by Western blotting.Results(i)The serum levels of E2 and ERα increased in the Qianggu Capsule group and HGMLP groups,compared with the model group(all P<0.05).(ii)Compared with the model group,the serum levels of PINP,TRACP-5b decreased and PINP/TRACP-5b increased in both the Qianggu Capsule group and HGMLP high-dose group(all P<0.05).(iii)The activities of T-AOC,AOD,and CAT in the Qianggu Capsule group and HGMLP groups were higher than those in the model group,while the content of MDA lower(all P<0.05).(iv)Compared with the model group,the femoral BMD,Tb.Th,and Tb.N increased in the Qianggu Capsule group and HGMLP groups,while the femoral Tb.Sp and SMI decreased(all P<0.05);the femoral BMD increased and the Tb.Sp decreased in the calcium carbonate group(all P<0.05).(v)The protein expressions of RANKL,RANK,FoxO3α,and PPARγ in the Qianggu Capsule group and HGMLP groups were lower than those in the model group,while the protein expressions of OPG,Wnt2,and β-catenin were higher(all P<0.05).Conclusion HGMLP can significantly increase estrogen levels,inhibit osteoclast differentiation,and inhibit bone resorption in the PMOP rats.It also alleviates oxidative stress,promotes osteogenic differentiation,inhibits lipogenic differentiation,improves bone formation,and recovers the balance between osteoclasts and osteoblasts,thus achieving prevention and treatment of PMOP.The potential mechanism of HGMLP may be related to regulation via the OPG/RANKL/RANK or FoxO3α/Wnt2/β-catenin/PPARγ pathways.

Objective The study aimed to elucidate the evolution of the syndromes in Traditional Chinese Medicine(TCM)and TCM syndrome elements in different chronic stages of psoriasis vulgaris.Methods A database was constructed using electronic medical records collected from July 2019 to March 2024 from 1,049 patients with psoriasis vulgaris.The study used Sankey diagrams and network association graphs to analyze the evolution of TCM syndromes and their elements in patients at the different stages:initial diagnosis,progressive stage(Week 2-3),progressive stage(Week 4-5),skin lesion improvement stage(Week 6-7),and remission stage.The syndrome elements network was constructed using community detection algorithms,and the association rules between local skin lesion syndrome differentiation and overall syndrome differentiation were displayed using heatmaps.Results(ⅰ)Initial diagnosis.In the syndrome differentiation of local skin lesions,blood heat syndrome was the most common(79.79％);among the disease location of TCM syndrome elements(called"disease location"),liver was the most prevalent(35.62％);and among the pathological factors of TCM syndrome elements(called"pathological factors"),fire(heat)was the most common(75.48％).(ⅱ)Active stage(Week 2-3).In the syndrome differentiation of local skin lesions,blood heat syndrome remained the most prevalent(73.13％);among the disease location,liver was still the most prevalent(31.71％);and among the pathological factors,fire(heat)continued to be the most common(82.11％),while dampness(22.26％)and qi stagnation(8.39％)began to increase.(ⅲ)Active stage(Week 4-5).The syndrome differentiation of local skin lesions was dominated by blood heat syndrome(45.91％)and blood dryness syndrome(37.19％);among disease location,the interior was the most prevalent(15.25％);and among the pathological factors,fire(heat)remained the most common(50.66％),with an increase in yin deficiency(34.26％).(ⅳ)Skin lesion improvement stage(Week 6-7).In the syndrome differentiation of local skin lesions,both blood dryness syndrome(49.44％)and blood stasis syndrome(33.33％)increased;among the disease location,meridians increased most significantly and became the most prevalent(13.44％);and among the pathological factors,blood stasis increased most significantly and became the most prevalent(28.20％).(ⅴ)Remission stage.In the syndrome differentiation of local skin lesions,blood stasis syndrome became the primary(55.69％),while the percentage of blood dryness syndrome decreased(21.16％);meridians(25.71％)and blood stasis(62.34％)remained the most predominant syndrome elements related to disease location or pathological factors.Conclusion The overall pattern of TCM syndromes in psoriasis vulgaris evolved from excess to deficiency.From the initial diagnosis to the active phase(Week 2-3),heat syndrome dominated;during the active phase(Week 4-5),heat syndrome coexisted with damp syndrome or yin deficiency syndrome;changes in the syndrome element network were the most significant during the lesion improvement phase,with blood stasis gradually increasing and peaking during the remission phase.Blood stasis,dampness,and qi stagnation were pervasive throughout psoriasis vulgaris;qi stagnation and blood stasis may be the main elements causing further deterioration and prolonged course of the disease during the active phase in patients.

Objective To investigate the difference of electrocardiographic(ECG)features between total left main artery(LM)occlusion and subtotal occlusion,and analyze risk factors of in-hospital mortality.Methods A total of 94 patients with left main complete occlusion and 99 patients with subtotal occlusion were included.ECG characteristics,coronary angiography and other clinical data were compared,and factors of hospital death were analyzed.The receiver operating characteristics(ROC)curve was used to analyze the predictive value of ECG characteristics in hospital death risk in patients with LM occlusion.The relationship between ECG characteristics,shock and collateral circulation were analyzed in patients with LM occlusion.Results Compared with the subtotal occlusion group,patients with LM occlusion presented with more ST-segment elevation(STE)in Ⅰ,avL,V2-V5,more STE in avR and avL,more left anterior fascicular block+right bundle branch block,prolonged QRS duration,less STE in avR and less STE in avR+V1.The in-hospital mortality was 46.8%(44/94)in LM occlusion and 14.1%(14/99)in LM subtotal occlusion.STE in avR+avL predicted total LM occlusion with a specificity of 0.97,and left anterior branch+right bundle branch block predicted total LM occlusion with a specificity of 1.00.In patients with total LM occlusion,STE in Ⅰ,avL,V2-V5,prolongation of QRS duration,shock,no collateral circulation,STE in Ⅰ,avL,V2-V5 combined with left anterior fascicular block+right bundle branch block,and STE in Ⅰ,avL,V2-V5 combined with shock predicted in-hospital mortality,with the area under the curve of 0.716,0.619,0.766,0.688,0.572,0.785,respectively.The diagnostic specificity of STE in Ⅰ,avL,V2-V5 combined with shock was 0.82,and the sensitivity was 0.75.STE in Ⅰ,avL,V2-V5 combined with left anterior fascicular block+right bundle branch block predicted in-hospital death in LM occlusion with a specificity of 0.94.The proportion of shock was higher in patients with STE in Ⅰ,avL,V2-V5,left anterior fascicular block+right bundle branch block and collateral flow absence(P＜0.05).In patients with total occlusion,no collateral flow was observed in patients with STE in Ⅰ,avL,V2-V5.In patients with STE in avR(including avR+V1),82.4%of patients presented with right coronary collateral circulation supplying the left anterior descending coronary artery and left circumflex artery territory.In patients with STE in avR+avL,69.2%of patients presented with right coronary collateral circulation supplying left anterior descending coronary artery territory.Conclusion Total LM occlusion presents with different ECG features compared with subtotal occlusion.In LM total occlusion,the ECG features predict in-hospital mortality and are associated with different collateral circulation.

Objective To analyze the risk factors for extrauterine growth retardation(EUGR)in late preterm infants appropriate for gestational age.Methods The clinical data in 1 402 preterm infants appropri-ate for gestational age delivered and hospitalized in this hospital from January 2016 to June 2022 were analyzed retrospectively.They were divided into the EUGR group(n=244)and the non-EUGR group(n=1 158)ac-cording to whether or not the body weight at discharge was below the 10th percentile of the growth curve for the same gestational age at the same period based on the Fenton's preterm growth curve.The clinical data of preterm infants and mothers of the two groups were collected.The risk factors for EUGR occurrence in pre-mature infants were analyzed.Results Among 1 402 preterm infants appropriate for gestational age,EUGR occurred in 244 cases with the EUGR incidence rate of 17.4％.The EUGR incidence rate had no statistical difference among the different fetal ages of premature infants(P＞0.05).The EUGR incidence rate had sta-tistical difference among different birth weights of premature infants(P＜0.05).The logistic regression anal-ysis showed that male(OR=1.694,95％CI:1.144-2.507),low birth weight(OR=0.989,95％CI:0.988-0.991),feeding intolerance(OR=2.719,95％CI:1.234-5.990),short gestational weeks(OR=0.146,95％CI:0.103-0.207)and hospitalization duration extension(OR=1.073,95％CI:1.031-1.117)were the risk factors for EUGR occurrence in late premature infants appropriate for gestational age in discharge.The sub-group analysis showed that male,low birth weight,feeding intolerance and hospitalization duration extension were the risk factors for EUGR occurrence in the preterm infants with gestational ages of 34-＜36 weeks(P＜0.05).Low birth weight and feeding intolerance only affected the preterm infants≥36 weeks of gesta-tional age(P＜0.05).Conclusion Strengthening the pregnant duration health care and active nutritional sup-port after birth may reduce the risk of EUGR occurrence in late premature infants.
